TSM924CSE+T

Overview

The TSM924CSE+T is a quad analog comparator in a 16-pin SOIC package. It operates on single supplies from +2.5V to +11V or dual supplies of ±1.25V to ±5.5V. The device features an internal 1.182V reference, push-pull TTL/CMOS-compatible outputs, and crowbar-current-free switching. Quiescent current is less than 2.5μA per comparator. Propagation delay is 12μs at 10mV overdrive. Continuous source current capability is 40mA.

Feature Summary

• Quad configuration with integrated voltage reference
• Push-pull outputs compatible with TTL and CMOS logic
• Ultra-low quiescent current consumption
• Crowbar-current-free output switching

Applications

• Threshold detectors
• Window comparators
• Level translators
• Oscillator circuits
• Battery-powered systems

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging rather than tube. Confirm the 'C' designation corresponds to the commercial temperature range of 0°C to +70°C. Ensure the component is sourced as lead-free. Check for obsolescence status as this family may have been discontinued.

Selection Notes

Select this part when four independent comparisons are required within a single package. The internal reference simplifies threshold setting compared to variants without it. Verify that the 12μs propagation delay meets timing requirements. Ensure the load does not exceed the 40mA continuous source current limit.

Part Context

This component belongs to the TSM921-TSM924 family of ultra-low-power comparators. It is electrically and form-factor identical to the MAX921-MAX924 family. The TSM924 specifically provides four comparators with an internal reference, distinguishing it from the TSM922 which lacks the reference.

Replacement Considerations

The datasheet states electrical and form-factor identity with the MAX924. Verify pinout compatibility before substitution.
